Hey, if the New York Giants can play in New Jersey, and still be the New York team, riding 9W can be a "training ride in New York." Pedantic much?
Now, he/she says it's 24 miles away and impractical, which is a different matter. Likewise, the Rockaways loop or Floyd Bennett would be impractical for me, whether they're within city limits or no. Not that I train for anything.
